Operators of such equipment require to be well trained in all aspects of High-Voltage Safety.
For the first time in the Indian sub-continent, customized training is now available to the Maritime sector. Designed and developed by IMTC, the “High-Voltage Safety Course” offers invaluable benefits to Marine Engineers and Electrical Officers.
The Course familiarizes the participants with High-Voltage equipment and the various safety procedures for handling the same. A 1-day field trip exposes the participants to the actual operations and maintenance procedures of High-Voltage switchgear at a High-Voltage installation.
Course Objectives:
To enable the Participants to :
- Understand the working of the various specialized components & equipment used in high - voltage installations.
- Operate, maintain & troubleshoot High Voltage installations safely & efficiently.
- Learn through sharing of experience amongst participants.
Duration: 3 days
Suggested Target Group:
All Electrical Officers & Marine Engineers.
